i have search in many sites but all are very technical and non seems to give a solution.

Azroy,You probably need to install Crystal Reports and their DLL's on your production server. That's a fairly common issue with third-party components -- they must be in the same location both your development and production environments in order for your generated application to use them.

i have install the full version of Crystal Report in my webserver. but then again when i run it i get same error.

please help me ......

regards
